We designed a comparative study to unravel the phylogeography of two Alpine endemic spiders characterized by a different degree of adaptation to subterranean life: Troglohyphantes vignai (Araneae, Linyphiidae) and Pimoa rupicola (Araneae, Pimoidae), the latter showing minor adaptation to hypogean life. We sampled populations of the model species in caves and other subterranean habitats across t...

Mitogenomes can provide information for phylogenetic analysis and evolutionary biology. The Araneae is one of the largest orders of Arachnida with great economic importance. In order to develop mitogenome data for this significant group, we determined the complete mitogenomes of two long jawed spiders Tetragnatha maxillosa and T. nitens and performed the comparative analysis with previously pub...

Male genital mutilation is a common mechanism by which males reduce sperm competition by plugging female insemination ducts with different parts of its own genital system. This behavior is frequent in many spider families but is uncommon in Haplogynae. The reproductive biology of Dysderoidea is not well studied and the data is fragmentary; male genital mutilation has been reported only for one ...

Spiders are one of the eleven orders of the class Arachnida, which also includes groups such as harvestmen (Opiliones), ticks and mites (Acari), scorpions (Scorpiones), false scorpions (Pseudoscorpiones), windscorpions (Solifugae), and vinegaroons (Uropygi). All arachnid orders occur in North America. Arachnida today comprises approximately 640 families, 9000 genera, and 93,000 described specie...

In Chile, all necrotic arachnidism is attributed to the Chilean recluse spider Loxosceles laeta (Nicolet) (Araneae: Sicariidae). It is predated by the spitting spider Scytodes globula (Nicolet) (Araneae: Scytodidae). The biology of each of these species is not well known and it is important to clarify their distributions. The aims of this study are to elucidate the variables involved in the nic...

O objetivo deste trabalho foi avaliar a macrofauna edáfica em plintossolos com cultivos agrícolas no município de Paraíso do Tocantins, região central Estado Brasil. Para as coletas foram utilizadas armadilhas queda (Pitfall) semanais período abril junho ano 2022. o estudo, selecionadas quatro áreas: Área 1 – Nativa, caracterizada pela vegetação cerrado; 2 - cultivada milho e próxima 1; 3 afast...

Cryptic habitats are often overlooked in biodiversity surveys. Phytotelmata, or plant pools, one type of cryptic habitat that supports diverse fauna a miniature ecosystem. This study surveys the arthropod community two types phytotelmata, bracts and leaf rolls, on single species, Calathea capitata (Ruiz Pav.) Lindl. (Zingiberales: Marantaceae), from Amazon site Peru. Specimens were collected ei...

during 2009, in the course of a faunistic survey of terrestrial parasitengona mites in jahrom region, ronaldothrombium bellator (southcott, 1986) (acari, trombidiidae) was collected and identified for the first time from iran. it was collected as ectoparasite of an unidentified araneae, which is a new host for r. bellator.

The behavior of amputating the legs spider prey by Cyphononyx fulvognathus (Pepsini, Pepsinae, Pompilidae) is reported for first time. was a female Heteropoda, presumably H. venatoria (Araneae: Sparassidae), which also record Heteropoda this wasp species. present observation found to be one uncommon examples amputation Pompilidae, common in species Ageniellini (Pepsinae).

Faunistical investigations of the 17th Biodiversity Days revealed occurrence 129 spider (Araneae) species in Csakanyospuszta, northernmost part Vertes Mountains, Hungary. Among collected there was 1 proteceted (Atypus piceus (Sulzer, 1776)) and were several rare ones to Hungarian fauna (Collinsia inerrans (O. P.-Cambridge, 1885), Entelecara flavipes (Blackwall, 1834), Metopobactrus prominulus 1...
